PQube-in-a-Box Installation Guide
Note: it is very important that installation of your PQube-in-a-Box (PQiaB) be
done by a qualified person, and in accordance with the local electrical guidelines
and codes.
PQube-in-a-Box
Important: ensure the PQiaB model you are installing matches the electrical configuration you are
monitoring:
If you have a neutral conductor
(Instrument will be powered from L1-N)
If you do not have a neutral conductor
(Instrument will be powered from L1-L2)
100V-240V Line to Neutral applications.
P/N: PQiaB-100V~240V-L-N-00
100V-240V Line to Line applications.
P/N: PQiaB-100V~240V-L1-L2-00
200V-400V Line to Neutral applications.
P/N: PQiaB-200V~400V-L-N-00
200V-480V Line to Line applications.
P/N: PQiaB-200V~480V-L1-L2-00
Installation
1.
Determine Location: The first step in installing your
PQiaB is to determine where you want to install it.
Typically, it is mounted using the 4 mounting holes
on the rear flange of the enclosure (unless you
selected the pole-mount option), and placed close to
the electric circuits you want to measure – often
adjacent an existing electric panel, for example.
2. Drill Conduit Holes: Protecting the wiring between
your PQiaB and the measurement points is important,
and this is usually achieved using PVC or metal
electrical conduit. Decide on the conduit size(s) you
will use, and drill the appropriately sized hole(s) for the
matching fittings in the bottom of your PQiaB
enclosure.

3.
Pull Wiring from panel: After mounting your PQiaB in the desired location, open the circuit breaker
protecting the electric panel you are monitoring, connect conduit, and run the electric wiring from the
panel to your PQiaB. This typically consists of connections to the voltage phases you are monitoring,
Earth connection, current sensors (if you are using them), and perhaps any analog or digital inputs, or
temperature humidity probe.
You may also have an Ethernet connection, but these often do not go to the electric panel. If you do
have an Ethernet connection, connect the cable through the low voltage conduit, or through a
separate opening.

Make PQiaB wiring connections: Your PQiaB is prewired so that your field connections are simple –
just strip your wires to ½”, release terminal block clamp by pushing orange lever with small screw
driver, and insert stripped wires. The Terminal Block wiring label inside the front lid of your PQiaB
clearly shows all possible wiring connections. Choose those that are right for your application, always
ensuring you have a good connection to the ground terminal.
Note: Terminal Block wiring connections for all 4 PQiaB models are shown at the end of this installation guide.
5.
If you are using an Ethernet connection, you will find the appropriate jack below the terminal blocks.

6.
Power Up PQiaB: When all your wiring is connected
and checked, close the breaker to the electric supply
you are measuring, and carefully test the voltages at
the terminal blocks on your PQiaB. If they are correct,
you can now close the 3-phase breaker in your PQiaB,
and your PQube will begin it’s power-up cycle.
7.
You can now close the lid of your PQiaB, as
you can access your PQube’s front panel from
the hinged window on the lid.
8. This completes the installation process, and all that remains, if not already completed, is the
configuration of your PQube using the PQube Configurator Program, available on your CD, or you can
download it from http: www.powerstandards.com/PQube.php#config
